Application filed September 90, L884.

To all who/7L it may concern.-

Be it known that we, BTARK V.\NDI:1RUO0.I(, WARD 1?. SMITH, and HENRY M.BAKER, residents of hlanton, in the county of \Vcxi'ord and State ofMichigan, have invented a new and Improved XVeight- Power Machine,- ofwhich the following is a full, clear, and exact description.

The object ol'our invention is to providea new and improved machine forutilizing weights as a power for lifting water or for other purposes.

The invent-ion consists in the combination, with the sprocketwheelmounted loosely on a shaft, and provided with a pawl adapted to engagewith a ratchet-wheel mounted rigidly on the shaft, of a chain passedover the sprocketwheel and having a weight suspended from its lower end,which chain also passes over a smaller sprocketwheel mounted on the sameshaft with a pulley over which an endless rope is passed, to be used forelevating the said chain and weight. A brake is provided which isoperated automatically, when necessary, by some of the levers of themachine.

The invention also consists in parts and details and combinations of thesame, as will be fully described and set forth hereinafter.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side view oi our improved weight-power machine, showing itin use for lifting water by means of a bucket. Fig. 2 is a front view ofthe same, parts being broken out and others shown in section. Fig. 3 isa longitudinal sectional view-of the bucket.

Two uprights, A, are united by a crosspiece at the top, and are suitablybraced and stiffened, and in brackets on the said uprights a shaft, 13,is journaled, 'on which is mounted l a pulley or wheel, 0, on one sideof which a grooved pulley, C, is formed, over which an endless rope, 1),passes.

On the shaft B a sprocket-wheel, E, is rigidly mounted, and over thesame a chain, F, passes, on one end of which a heavy weight, F,.issecured. The chain also passes over part of a sprocket-wheel or toothedwheel, G,

the teeth of the said wheel G engaging with (X0 model.)

the links of the chain. The said wheel G is loosely mounted on the shaftH, and is provided with a pivoted pawl, G, adapted to engage with aratchet-wheel, I, rigidly mounted on the shalt H adjacent to the wheelG.- A suitable spring secured on the wheel G presses the pawl againstthe teeth oi'the ratchet-wheel I. A cog-wheel, J, rigidly mounted on theshaft H, engages with a pinion, K, rigidly mounted on a shaft, L, onwhich a drum, M, having a spiral groove in its rim, is loosely mounted,arope, N, being secured to and wound on the drum, from the lower freeend of which rope a bucket, 0, is suspended which is provided with abail, O. The drum M is provided with a ratchet-hub or clutch-hub, M,adapted to engage witlrihe clutch-sleeve m, which turns with the shaftL, but is adapted to slide on the same, and is connected with a lever,P, pivoted on a cross-bea1n at P, and having its upper end pivoted to atransverselysliding bar, Q. A spring, in, surrounds the shaft L, and isconnected with the drum M at one end, the other end being rigidly heldto the frame. The lower end of the lever P is so located that the bucket0 will act on it. The bucket is provided in its bottom with an openingclosed by a valve, R, adapted to open upward, and on its top edge thebucket is provided with a hook, 0" adapted to catch on a wire bail, 1%,at the upper end of the spout it. A brakeshoe, a, is pivoted to alever,Z), pivoted to the cross-piece uniting the standards A, to which lever ba bar, 0, is pivoted, which is provided at its lower end with a slotthrough which the bar Q. passes. The bar Q also passes through theforked end of a standard or bar, S, provided with a pin, (7, passingthrough a slot, f, in the bottom of the bar 0. The bottom edge of thebar Q, is beveled or rounded at g, and a shoulder, h, is formed ashortdistance from the end on the bottom edge.

The operation is as follows: The weight is raised by turning the shaft Bfrom the pulley-wheel O O by means of the endless rope D, whereby thesprocketwheel E lifts the chain F and the weight F, suspended from thesame. The bucket is at the bottom of the well or cistern, and theclutch-collars M and m are disengaged, and the brake-shoe cvis loweredand rests on the rim of the pulley O,

- thus preventing the said pulley from revolvmachine.

ing, and thereby locking the weight in place and stopping the entiremachine. IVhen the machine is to be operated, the bar Q is pushed in thedirection of the arrow (4 until that part of the bar between theshoulder h and the end rests upon the forked bar S, whereby the bar 0 israised and raises the brakeshoe (1 from the rim of the wheel 0, thuspermitting the weight to descend and to revolve the shaft L. By movingthe bar Q in the direction of the arrow a the clutch-cot lar m isengaged with the clutch collar M, whereby the drum M is revolved, andthe rope N wound on the same, and the bucket raised. Then the bucketarrives at the top, the hook O catches on the bail R, whereby the bucketis swung into a horizontal position, so as to permit the water to flowout into the spout on the lower end of the lever P and moves the lowerend of the said lever in the direction of the arrow a, thereby movingthe bar Q in the inverse direction of the arrow a, and pushing theshouldered part of the said bar off the forked upper end .of the bar S,thus permitting the bar 0 and the brake-shoe to drop. The brake-shoelocks the several parts above mentioned in place, and prevents thefarther deseent of the weight F. IVhen the apparatus is again to beoperated, all that is necessary is to push the bar-Q in the direction ofthe arrow a. The bucket 0 descends immediately after it has beenemptied, and is filled automatically through the opening in the bottom.The spring at is coiled by the unwinding of the rope from the drum M,and equalizes and regulates the unwinding of the rope.

According to the size of the weight F and the. arrangement of thegearing more or less work can be performed by the weight-power Forinstance, the weight may be so adjustedthat by raising the weight once,five, six, ten, or twelve buckets of water can be raised by the descentof the weight before requiring the weight to be again raised.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent- 1.
